Good News: I have modified the file so they stack into one single order. Bad news: 10.5 inches once assembled really is the better 'medium' option and it's expensive. I'm not marking up my models a huge amount, and it's still $80 to order for myself in medium. 9 inches once assembled was screen accurate and is the new 'small' size, but you have to be pretty tiny to pull it off.
ETA: I have added size options!
UPDATE: Photo added. The first one came out about 9 inches across, which was fine for Carrie, but too small to be 'medium'.
I'm going to make some updates to the model. The print came out nice, but I think the wire detail needs to be larger. I'm going to rebuild the spheres to try to cut down the polygon count enough to get it in one file instead of two. (UPDATE) I did these things.
I built this model.
